HEEL-COMPRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 376.754, dated January 24, 1888.

Application filed November 2, 1587. Serial No. 254,040. (No model.)

2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Heel-Compressing Machines, of which the following is a full, clear, andexact description.

The invention relates to a heel-compressing machine having a rotary die-holder and dieblocks carried thereby, and a reciprocating head carrying one or'more heel-seat formers.

In the drawings, Figure 1 is a view of the machine in front elevation Fig. 2 is a view of the upper part of the machine in vertical section upon the vertical dotted line of Fig. 3. Figs. 3 and '5 areviews representing slight modifications, and Fig. 4 is a detail view.

Referring to the drawings, A is a crosshead. Itis reciprocated vertically, preferably by means substantially as described in the patcut to Henry A. Henderson, No. 316,894. It supports an arm, a, carrying a heel-blank former, A. This arm a may be fixed or the cross-head mayfsupport a rotary head, as represented in Fig. 1, having a number of arms a, each of which supports aformer, A. Upon the bed or table B of the machine is mounted a bracket, b, which'supports or carries a drum or rotary support, B. This drum is rotated upon the stationary shaft b, which is carried by the bracket or support b. The drum or rotary support also has a number of die-hold; ers, b", arranged in or upon its circumference, each of which is adapted to receive a dieblock, 0. Each die-block has a die-recess, c, of a shape to form the sides and breast of the heel, the flaring mouth 0', and a movable diaphragm, c, which forms the bottomof the die. This diaphragm is of metal and has a downward or inward extending stem or spindle,- 0 which passes through a hole in the bottom of the die-block, and is adapted to be moved from the center of the rotary block D by means of the incline c on the shaft 5. Fig.2.) This wedge c is placed so that the diaphragm c is moved outwardly when the die-block has been turned so as to cause its opening to be downward instead of upward,

(Seev a The rotary block or holder B is given an intermittent rotation by means of the ratchetwheel E, secured thereto, the pawl e, which is hung upon the lever e, pivoted at e, and the link I), which connects the lever c with the cross-head. The pawl and ratchet are so arranged that'the rotary block or holder-is" moved upon the upward movement of the cross-head only, and is stationary during the downward'movement of the cross-head and former A in relation to the die, so that before starting the machine the operator places.- a

heel-blank in the cavity of the die in advance of the one to be compressed, and upon the downward movement of theplate the said.

heel-blank is compressed and itsseat formed,

and uponthe upward movement an uncompressed and unformed heel on the die is fed automatically into position.

means of a friction-clamp, F, which bears against the side of the rotary block. The dieblocks are held in place upon or to the drum by spring-latches, or in any other desired way.

The advantages of the invention arise from the rapidity with which the'heel is compressed and heel-seat formed, the formed heel-blanks The rotation of the block B is checked upon I v the end of-the feed movement of the pawl e by being automatically removed from the dies'and if he were obliged toplace the heel-blank in.

the die immediately underthe former, and the die-block having its mouth orentrance upward at thattime enables this to be done readily,so that the capacity of the machine is verygreat,

the operator simply having to put the heelblanks into the open cavities of the dies and start the machine.

I would say that the rotary block B may be sufficiently wide to hold two or more dieblocks in line and that the cross-head A. may carry a heel-seat former for each'die blo'ck. (See Fig. 3.) .I would also say that the rotary block may support sole-compressing molds or formers instead of heel-compressing molds or formers, as represented in Fig. 5, in which event the cross-head would also support asoleforming section. Any form of mold or former suitable for this purpose may be used. I prefer that the concave die or former be carried by the block or holder and that the convex die or former be carried by the reciprocating head.

The machine may be organized to stop after every reciprocation ofthe former, as described in said Henderson patent, or to run continuously.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States.

1. The combination of the head A, a reciprocating former, A, carried thereby, the rotary block B, adapted to be rotated upon the horizontal shaft 1), the bracket or support I), and the die-blocks O,carried thereby, substantially as described.

2. The combination of the reciprocating head A and former A, carried thereby, the rotary block B, the horizontal shaft b, upon which it is mounted, the die-blocks 0, carried by said block or holder, the diaphragm having the spindle ciand the wedge or incline cfiarranged upon said shaft to operate as specified, all as described.

3. The combination of the head A, former A,carried thereby,the block B, mounted upon a horizontal shaft, b, the die-blocks 0, carried thereby, and devices for rotating the block during the upward movement of the crosshead, substantially as described.

4. The combination of the head A, the former A, carried thereby, the rotary block B, mounted upon a horizontal shaft, the dieblocks C, carried by said block or holder, the heel-dischargcr 0, adapted to be operated upon the rotation of the die-blocks to bring their openings below the diaphragm, with a device for rotating the block or holder B during the upward movement of the cross-head, substantially as described.

5. The combination of thehead A,theformer A, the head or holder B, the die-blocks 0, carried thereby, the ratchet-wheel E, pawl e, lever c, and links e, connecting the lever and crosshead A, substantially as described.

6. The combination of the cross-head A, two or more arms, a,'carrying a former, A, with the rotary block or holder B, mounted upon a horizontal shaft, 5, and die-blocks 0, carried by said holder or block, substantially as described.

7. The combination of the head A, two or more arms, a, carried thereby, a heel-former, A, for each arm, the rotary block or holder B, and two or more die-blocks, 0, arranged in the same horizontal line upon said block or holder, and adapted to be brought simultaneously into operative position, as and for the purposes specified.
